noun
A precursor cell for chromaffin cells.
noun
A hypothesized cell, arising from the neural crest, that serves as a common progenitor cell for pigment cells, especially in some fishes and amphibians.
Example Sentences
- "Possibly more than one type of chromoblast precursor is present in the adrenal primordium[.] TH levels are lower in chromoblasts that have migrated into the adrenal primordium and that are destined to become future neurones or NA cells than in future A cells[.] [figure legend]"
- "During embryogenesis, chromoblasts destined to become either adrenaline- or noradrenaline-secreting cells migrate in small homotypic groups independently into the gland along unmyelinated nerve fibres with the consequence that the two chromaffin cell phenotypes have different innervation and thus respond to different stimuli (Leon et al. 1992; Edwards et al. 1996)."
- "PPGL [pheochromocytoma and paraganglioma] similarly occur at respective intra-adrenal and extra-adrenal locations, but originate from chromaffin cells or their chromoblast precursors, and are usually detected in adulthood though may be overlooked in childhood."
- "The morphological changes are accompanied by the establishment of a well-differentiated dorso-ventral pigmentation pattern. In the ocular side, stem chromoblasts differentiate into adult chromatophores (mainly melanophores, xanthophores and iridophores) and larval chromatophores progressively disappear."
- "Similar to other vertebrates, fish pigment cells are developed and differentiated from neural crest cells during early embryonic development [4]. Neural crest cells are first developed into chromoblasts and then differentiated into chromophores."
- "The three primary pigment cell types arise directly from a neural-crest-derived progenitor cell (chromoblast) with a tripotent pigment organelle. Fate specification of the chromoblast is determined by genetic and environmental factors that affect the formation of pigment-producing organelles. [figure legend]"
